4. Air Handler: The air handler is the unit responsible for circulating the cool air throughout your home. It consists of a blower, filter, and sometimes, additional heating elements.
5. Ductwork: The ductwork is the network of pipes or channels through which the conditioned air flows from the air handler to different rooms in your home.
6. Thermostat: The thermostat is the control panel that allows you to regulate the temperature and settings of your air conditioner.

Now that we have a basic understanding of the various components that make up an air conditioner, let’s focus on the role of the coil and why it is a critical component in the cooling process.

The Role of the Coil in an Air Conditioner

The coil plays a vital role in the cooling process of an air conditioner. In simple terms, it acts as a transfer point for heat exchange, allowing the refrigerant to absorb heat from the indoor air and release it outside. The coil is divided into two parts: the evaporator coil and the condenser coil.

The evaporator coil, also known as the indoor coil, is responsible for absorbing heat from the indoor air. As warm air from your home is blown over the evaporator coil, the refrigerant inside the coil absorbs the heat, causing the air to cool down. This cooled air is then circulated back into your home, providing a refreshing and comfortable environment.

On the other hand, the condenser coil, also known as the outdoor coil, plays a crucial role in the heat dissipation process. As the refrigerant carrying the absorbed heat flows through the condenser coil, it comes into contact with the outside air. The heat from the refrigerant is released to the outdoor air, effectively cooling down the refrigerant so that it can start the cooling cycle again.

Without the coil, the heat exchange necessary for cooling your home would not be possible. It is the coil that enables the transfer of heat from the indoor air to the refrigerant, and from the refrigerant to the outdoor air. Therefore, maintaining the coil and ensuring its optimal performance is key to efficient cooling and energy savings.

Now that we understand the role of the coil in an air conditioner, let’s dive deeper into the different types of coils you can find in air conditioning systems.
